Franklin Tung appears in The Double Death of the Dearly Departed. After the murder victim Hank came to him for embalming, he accidentally hit a nerve and Hank, who was not dead sat up in reflex. Panicked because of watching too many zombie movies, Franklin stabbed him seven times, killing him. He was forced to hide the fact that the Jeffersonian team had stolen Hank's body to do an autopsy.
Its unknown if Franklin faced any charges since he did kill Hank even if by accident. However, it doesn't seem likely as Franklin was at Hank's service the day after his actions were discovered.
